I recently had my W850i that was locked and branded on oragne unlocked at my local phone shop. All worked fine but I hated the stupid orange load logos and branding, so I recided to follow this guide: htttp://forums.se-nse.net/index.php?showtopic=15734 My only problem is now after a sucessful debranding / flashing it loads with Sony Ericson screens but the phone always says "please insert correct sim card". Has flashing the phone re-locked it on orange? Did I select the wrong CDA (Central Europe Generic)? How do I get it to accept my Tesco Mobile sim card (which as I understand uses 02 network). Any help would be MASSIVLY appreciated, this is as much a learning excersise for me as saving money walking down to the shop and paying some one else. Thankyou, for this great forum and any replies!
